Cobalt-6

Deep, dense cobalt blue; the darkest of the GA cobalt range. Work in a neutral flame — reduction causes gray streaks.

Outcomes

• Dense, very dark cobalt blue flame: NeutralBlueIndigo
  Work in a neutral flame to maintain clean, deep cobalt color. Ideal for millefiori work and stringer pulling where a dense dark blue is needed.
• Dark cobalt blue with gray streaks (over-reduced) flame: ReducingBlueGray
  A reducing flame causes gray streaks in the glass — an undesirable result. Keep the flame neutral to avoid this.
